Geek Fun&games!

Gigabytes of fun stuff&activities

To achieve perfect work/leisure balance at this year's conference, we have prepared gigabytes of fun stuff and activities for you to enjoy while taking a break from soaking up the knowledge.

  • Retrogaming

    In between and after the lectures find your way to our special retrogaming room and travel back to where it all started. Be sure to check out the video games from the 90s in our timetable and participate in TGG retrogaming tournaments with prizes and all!

    You don't need a conference pass to take part in TGG retrogaming – it's free and it's open to everyone who is interested. All it takes is having a true gamer's passion.

    Retrogaming is not complete without retro music, so we will be playing oldies to make the atmosphere even more authentic.

  • Live Concert — The Bambi Molesters

    The Geek Gathering is a conference that appreciates fine music and its atmospheric importance, which is why we are happy to announce this year's TGG performers: The Bambi Molesters! With their recognizable sound, the Bambi Molesters have managed to spread the word that surf rock is not dead! Garage punk, spacey psychedelia instrumentals and spaghetti western mixed in their energetic performance create an unforgettable experience you don't want to miss.
